Conrad released a new upstream release
4.200 for Armadillo, his templated C++
library for linear algebra, earlier today.

As usual, this was rolled up in a new
RcppArmadillo
release 0.4.200.0; I had actually made two pre-releases leading up his 4.200
release and was hence not expecting any surprises. Prior to uploading to
CRAN, I also tested against all 61
reverse dependencies of the package. Last but not least, I also updated the
corresponding Debian package.

Changes in RcppArmadillo version 0.4.200.0 (2014-04-07)

  • Upgraded to Armadillo release Version 4.200 (Flintlock Swoop)

    • faster transpose of sparse matrices

    • more efficient handling of aliasing during matrix multiplication

    • faster inverse of matrices marked as diagonal

Courtesy of CRANberries, there
is also a diffstat report for the
most recent release
As always, more detailed information is on the RcppArmadillo page.
Questions, comments etc should go to the
rcpp-devel mailing list
off the R-Forge page.
